JOHN A. MARDEN, OF HINSDALE, NEW HAMPSHIRE.

STEAM-COOKER.

SPECIFICATION forming part of Letters Patent No. 325,100, dated August 25, 1885.

Application filed August 28, 1884. (No model.)

To all whom it may concern.-

Be it known that I, JOHN A. MARDEN, a citizen of the United States, residing at Hinsdale, in the county of Cheshire and State of New Hampshire, have invented certain new and useful Improvements in Steam-Cookers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanymg drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in steam-cookers, and it consists in the constructron and combination of parts as hereinafter described and claimed.

. In the annexed drawings, Figure 1 is an elevation of my improved steam-cooker, and Figs. 2 and 3 are vertical sections of the same on different lines.

A and B represent two sections ofa steamcooker fitted together in the usual manner, and provided with perforated transverse partltions a b for supporting food. The upper section, A,is provided with a cover that is also capable of fitting the lower section, B, when it is desired to use the latter alone. On the outside of each section of the cooker is a tube that communicates with the interior through an orifice, as c or 0, thereby forming a G, for the escape of odors and waste steam, and whereby they are conveyed downward through the open lower end of the conduit into the fire.

E denotes an indicator, which moves in a slot, 0, in the side of the cooker, and is fastened to a float, Gr, sliding within a box or casing, H, within the lower vessel, so that by means of this indicator the height of the water in the boiler can at any time be easily ascertained.

F is a funnel, having atits bottom a small aperture, f, through the side wall of the cooker. By means of this funnel the supply of Water can at any time be quickly and easily replenished.

In the upper compartment I find it is most advantageous to place an oven, D, constructed of sheet-iron, which is so placed within this compartment that the steam may pass easily around and underneath. This oven is provided in its interior with a rack, I, of cross-bars. which rests on an interior convex bead, and is designed to support the food. The oven is also provided with a bail, and it has a ti ghtly-fittin g cover, so that steam cannot pass within the oven.

I am aware that cookers have heretofore been constructed with an external or internal conduit, also with an indicator for showing the depth of water in the boiler; but I am not aware that any one has as yet shown a method of using these attachments similar to that described in this specification.

My method of filling the boiler is superior to those before employed, for I combine the advantage of a constantly-open funnel, through which to replenish the water, with that of an indicator in close proximity thereto, which shows at all times the height of water in the cooker, and with the further advantage of an entire freedom from escaping gases and steam, which is acquired by the use of the internal casing open only at the lower end.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with a steam cooker having on one side an external funnel, F, vertical slot 0, and perforation f, of an interior vertical casing, H, open only at the bottom, and a float, G, inclosed in said casing, and provided with a bent indicator-arm, E, that is capable of a vertical movement in the slot 6, whereby the movement of the indicator can be observed and the vessel filled when required through the funnel F, and communicating perforation f, without permitting the escape of steam, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
